First, take an empty glass bottle and fill it with tap water. Then put the sea baby in it. Remember to change the water once a day, otherwise it will stink easily.

It usually takes three or four days to grow up quickly, so don't worry.

Remember the sea baby soaked in water, don't always like to play with your hands, this is not good, it will affect its growth.

Note: Haibao is made of absorbent sponge, which dries very little and will swell immediately when it comes into contact with liquid. Because the "sea baby" will continue to expand, it is more dangerous than foreign bodies such as peanuts and walnuts. "After inflation, it completely blocks the airway, and oxygen cannot be sent in." Toys like "sea baby" are both attractive and dangerous. Please don't let children play with them. If you eat by mistake, please seek medical attention as soon as possible.
